Using the law of sins:

Sin(angle) = Opposite Leg / Hypotenuse

Sin(30) = AB /10

Solve for AB:

AB = 10 * sin(30)

AB = 10 * 1/2

AB = 5

The answer is A.

Answer:

Part 1) The area of the figure is $A=48\ cm^2$

Part 2) The perimeter of the figure is $P=4(2+3\pi)\ cm$

Step-by-step explanation:

Part 1) Find the area of the figure

we know that

The area of the figure is equal to the area of three squares

$A=3[4^2]=48\ cm^2$

Part 2) Find the perimeter of the figure

we know that

The perimeter of the figure is equal to two times the length side of the square, plus the circumference of six semicircles ( or the circumference of three circles)

Remember that

The circumference of a circle is equal to

$C=\pi D$

where

D is the diameter of the circle

In this problem

$D=4\ cm$

$P=2(4)+3[\pi(4)]=(8+12\pi)\ cm$

simplify

$P=4(2+3\pi)\ cm$

Answer:

<h2> Driver B has the fastest race time</h2>

Step-by-step explanation:

From the options presented, driver B has the fastest typical race time because he recorded the smallest time taken to complete an individual race.

Also from the standard deviation given (3.96) for driver B, it shows that the individual time spread from the standard deviation is minimal and that the driver maintained a fairly consistent time of race throughout the racing period.
